janu16 · Answer

3.14•10^2

nnesha · Answer

i guess you don't have to use pi

parissfrance09 · Answer

is it 400??

nnesha · Answer

$$A = \pi \times r \times r$$
replace r by 10
and if you don't use pi value then  answer is there

@parissfrance09 
Are all answers supposed to have $\pi$ in them but  by copying the problem, it was left out?

anonymous · Answer

Yes

parissfrance09 · Answer

leave pi out

nnesha · Answer

okay so please try to type your question instead of copy paste 
and also its in coc ( CODE OF CONDUCT)

mathstudent55 · Answer

$A = \pi r^2$

$A = \pi \times (10 ~in.)^2$

$A = 100 \pi ~in.^2$

anonymous · Answer

It is 400 because a diameter of 20(radius 10) would be at least 314

If the diameter of the circle above is 14 mm, what is the area of the circle?
49 pi mm2
7 pi mm2
196 pi mm2
14 pi mm2

nnesha · Answer

i'm pretty sure i already gave u all formulas right use that and let me know what you get

parissfrance09 · Answer

okay

nnesha · Answer

:-)

nnesha · Answer

use formula a = pi times r times r
now for this question they gave ou diameter
so radius is half of diameter 
so divide diameter by 2 the number you get that u suppose to substitute into r(radius)

mathstudent55 · Answer

Find the radius by dividing the diameter by 2.
Then multiply the radius by itself and by pi.
